Raised in genteel poverty after the first World War, Maria Magdalena Dietrich dreams of a life on the stage. When a budding career as a violinist is cut short, the willful teenager vows to become a singer, trading her family's proper, middle class society for the free-spirited, louche world of Weimar Berlin's cabarets and drag balls. With her sultry beauty, smoky voice, seductive silk cocktail dresses, and androgynous tailored suits, Marlene performs to packed houses, and becomes entangled in a series of stormy love affairs.
